n. Using massive amounts of weak, or generic units, to attack an enemy.
Used widely in PlanetSide, to describe massive amount of soliders that spawn in a tower, and then attack a base.
It comes from the word wordzerg/word. Zergs in Starcraft were able to produce large amount of units very quickly.
It's when you don't know where you are and continue your adventure. You are as lost as Zoro Roronoa from One Piece.
